SPECIFICATION forming part of Letters Patent No. 576,129, dated February 2, 1897. Application fil d December'26, 1895. Serial No. 573,304. (No model.)

To all whom it may cancer/2.:

Be itknown that I, LEOPOLD J ULIG, a sub- ,ject of the German Emperor, residing in the city and county of San Francisco and State of California, have invented certain new and .useful Improvements in Electrical Advertising Devices, of which the following is a specification.

My invention relates to the production of an improved device for advertising purposes to direct the attention of passers-by to the contents of a store-window and for exhibiting goods and articles of various kinds in such and similar situations.

The invention consists in the described construction and combination of parts and an advertising and goods exhibiting device produced therefro as hereinafter fully set forth, reference being had therein to the drawings that accompany and form part of this specification.

In the said drawings, Figure 1 is an elevation, principally in longitudinal section, of a device constructed according to my said invention. Fig.'2 is a horizontal cross-section taken through the line y y, Fig. 1. Fig. 2 is a diagram illustrating the electrical circuits through the parts of the mechanism. Fig. 3 is a view in perspective, on an enlarged scale, of the upright spindle, the electric motor and the connections between the shaft and the spindle driven by it.

A indicates a stationary base or stand, on which is mounted to revolve about a central upright post B a flat circular table 0.

D indicates a light globe or sphere fixed on an upright rod or shaft E, for which bearings ff are provided on the table C.

The principal parts of a small electric mo tor, comprising a pair of spools G and a vibrating armature G on one end of an oscillating lever G", are mounted on the table 0,

V and the outer end of that lever is connected by a pitman I and bya wrist-pin h on the end of the shaft to one end of a commutatorshaft H on the stationary frame beneath the table. By alternately energizing and deenergizing the magnets the armature G is drawn to the poles of the magnet from the extreme highest position or the extreme lowest position of the lever G to a position on the center and is caused to pass over the center to the opposite position, first, by interrupting the current and deenergizing the magnet as the armature comes on the center, and, secondly, by the momentum of the parts to which the outer end of the lever is connected. In this manner the oscillating motion of the lever G2 is caused to rotate the shaft I, to which the lever is connected, as before stated.

The current to run this motor is taken from an electric-light circuit by insulated conductors S and T, connected under the base A of the stationary frame to parts that bring into circuit the spools G and the armature G. This connection is made or carried through the commutator H .on the shaft II by spring tongues or brushes which make and break the circuit at the proper times in the movement of the armature across the field of the magnet G, and soproduce vibratory motion of the lever G The shaft H, supported at the outer end nearest the crank h by a bearing in the stationary bracket 11, is geared into the spindle E by bevel-gears H II, and the commutator I-l is formed on the portion of larger diameter nearest the bearing. Upon such part H the brush composed of the spring-tongue M is set to act, and upon the enlarged part of the shaft next this commutator the contact-spring N is arranged to hear at its outer end in continual working contact. These two springs M N 2 are secured to the stationary arm or bar that is supported by the bracket H, and to this same support the contact-springs N N are attached. To and through these parts electrical connection is made and the circuit from the two covered wires S T is carried in the following manner:

The uncovered end of one wire S is made fast to the lower part of an insulated conducting-rod or wire S that extends upward through the center of the stationary post B of the frame. At its upper end the conduc tor S is uncovered, and a contact-spring S secured to the bracket K" on the top of the hollowpost K, but insulated from it, bears against such uncovered end of that conducting-wire. To this spring S is connected one end of the coils of the spools G by the Wire 9 and to a similar contact-spring S secured on the fixed arm F, the other end g of the spool-winding is connected. A spring ICO S", bearing against the upper end of the spindle E, and the lower end of that spindle bearing on the fixed ring L of the base A, makes electric connection of the spindle with that ring. The spindle E and the ring L are insulated from all other parts of the frame, and through the said parts the current from one pole of the battery is brought to the brush M of the commutator H From the other pole, to which is connected the conducting-wire T, the circuit is carried through the cylindrical block T and from that piece to the hub or enlarged portion on the shaft H by means of the contact-springs N N so that the circuit from S passes through the spindle E, ring L, and by spring N to brush M, through the commutator II and the springs N N to T to the wire T.

The commutator I-l is properly adjusted to break circuit through the brush M when the armature is on the center opposite the poles ofthe magnet, but to close the circuit as the armature reaches its extreme positions upward and downward in the vibrations of the lever. \Vhen the armature is opposite the poles of the magnet, the crank-pin his on the center and the lever G is horizontal.

The spring N is connected electrically to the brush M, and its free end bearing against the inner side of the ring L makes electrical con tact therewith as the parts to which the spring N is connected revolve about the upright central shaft.

The drum or cylindrical case is supported by arms XV from the table C and is rotatable on the base, so that it may be turned and set in different positions to bring to view at the front such articles as may be attached to or secured on the face of the drum for exhibition.

The table 0, supported by the hollow post K, is fitted thereon to turn freely around the fixed post B, and the bracket F, fixed on the table, is provided with a socket K in which is fixed an incandescing-lamp U. The circuit for this light is derived from the circuit of the motor by carrying one wire 0 from the lamp to the upper end of the fixed tube S, that extends through the post B from top to bottom and projects above the top end of that post. Such tube is insulated from the post by an insulator V, and at its lower end is connected into the conductor T under the base by the short wire 6, and the other wire S of the lamp is connected into the circuit at the contact-spring S Thus the lampcircuit is established around the commutator and is not affected by the making and breaking of the motor-circuit at the commutator.

The conductors extending through the upright post are separated from one another by the insulators V V.

Having thus fully described my invention, what I claim as new therein, and desire to secure by Letters Patent, is-

The combination, with the stationary base and the table rotatable thereon; of the revoluble globe on an upright spindle which is also a conductor, the stationary magnets, the vibrating armature-lever carrying on one end an armature arranged to move across the field of said magnets, the rotatable shaft one end of which is geared into the globe-spindle and .the opposite end connected to the armaturelever by a crank and pitman, the commutator on said shaft, the stationary arm and the commutator brushes secured thereto one brush arranged in working relation with the cut-away portion of the commutator and the other brush set to make continual contact with the cylindrical portion of the shaft next the commutator, the conducting-ring with which the lower end of the globe-spindle is in electric contact, the contact-spring connecting the commutator-brushes with such ring, and the contact-spring completing the connection electrically between the said brushes and the central post of the structure, and the springs and connections completing the circuit through the said parts between the wires from the two poles of an electric battery, constructed for operation as set forth.

In testimony that I claim the foregoing I have hereunto set my hand and seal.
